💖 radeon_combios_init(9) 💖

okay bestie, welcome to the Kernel API Manual — we're doing a little driver lore today and honestly it's giving niche-but-iconic ✨

---

🌸 NAME 🌸

radeon_combios_init — literally just inits the driver info for combios, that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

int radeon_combios_init (struct radeon_device *rdev );

---

🫶 ARGUMENTS 🫶

• rdev — a radeon_device pointer. that's it, that's the whole argument. she's low maintenance 💅

---

🔥 DESCRIPTION 🔥

so what does she actually do? she initializes the driver info for combios (that's the r1xx–r3xx era, vintage darling 🎀). returns 0 on success — no cap, zero is the good number here 👑

called at driver startup, so she's one of the first ones on the scene, main character energy fr fr. ngl, nothing dramatic, she just sets things up so the rest of the driver can slay 🌈
